Some people report that power regenerator limit dynamics. The peak current demands of power amplifiers can greatly exceed their nominal rating. I have been very pleased with the performance of my Equi-tech 1.5 kVa balanced power supply. Essentially it’s a very large ~30kg toroidal transformer feeding multiple outlets from a 20 amp mains outlet. The thing is, I don’t know if it “translates” to UK power. In North America, household power is supplied as single phase 120 volts. This is delivered by a 3-conductor system: 1 wire is “hot,” 1 wire is “neutral” and 1 wire is ground (earthed). At the circuit breaker box where the main power enters the building, the neutral wire is tied to the ground wire. So, the potential difference between hot and neutral is 120v and the potential difference between neutral and ground is zero. Under normal operation, the electricity flows between hot and neutral, and the ground is for safety. A balanced power supply splits the 120 volts into 2 60 volt legs, running 180 degrees out of phase with each other. The hot wire carries one phase and the neutral wire (on the output side of the transformer) carries the other phase. The ground carries no electricity. So, because of the phase relationship, the potential difference between hot and neutral is still 120 volts. Because of common mode rejection, much of the noise is attenuated; and the very large inductor stores energy to accommodate peak current demands. I have noticed the effect of this is to significantly improve the performance of two different CD players I have owned and also two different subwoofers. PS Audio’s regenerators also deliver balanced power.
What I don’t know is how this translates to a British system. In the US 220-240 volts also is supplied to houses for high-demand uses such as cooking stoves and ovens, clothes dryers, domestic hot water heaters and central air conditioning systems. That is supplied in balanced form. There are 3 conductors, 2 hot and one ground. Each out conductor carries 120 volts, but they are 180 degrees out of phase with each other. So, the potential difference between them is 240 volts. So, it may be that, in the UK you are already receiving balanced power. If that is the case, then North American power conditioners, etc., which are designed for the single-phase 120 volt system, will be of no use to you. A 240 volt version of a PS Audio power plant may be of some use (because the power is regenerated and voltage-stable), but it will not provide you with nearly the benefits it provides a North American customer because you are already getting balanced power.
Sorry for the length of this.
